[5][6] The protein encoded by this gene associates with stem loop IV of U2 small nuclear ribonucleoprotein (U2 snRNP) in the presence of snRNP-A'.

The encoded protein may play a role in pre-mRNA splicing.

Autoantibodies from patients with systemic lupus erythematosus frequently recognize epitopes on the encoded protein.

Two transcript variants encoding the same protein have been found for this gene.
